APEARAEUQ 3GB MAKING EIEEE-SLUGS.

' Cleveland; in: the. county of Gayahcga and State of Ohio, haave invented a. certain new and useful Improvement in, Apparatus for Making Line-Slugs, of which the following is a. tall, clear, and exact description, reference being had to the accompanying drmvings.

My prior application No. 783,722, filed August 8th, 1913 describes and claims a process of making short height-to-paper line slugs having holding devices on their opposite sides, such piroeess, briefly. stated, consisting of the steps casting a slag in a: T-form with ribs on its sides, and thereafter breaking down. the upper. portion of the ribs and removin the lower portion of the sing to make a snort sing with lags on. its sides separated from its head llhe object 01" the present invention is to provide an ehicicnt mechanism for casting the'hlank from which such finished slug; is made by reinoaing the lower portion and breaking down. the side ribs.

The present invention relates to a. pcculiar mold for casting such slug and a peculiar ejector for removing the original slog from the mold, both these pests being adapted for mounting. inthe standasd; Mergentlialer machine.

The invention is hereinafter more fully explained nd. its essential chasacteaistics set out in. the clahns.

cam 20, mounted ona rotatable shaft 21 and adapted to reciprocate the slide,

The wheel 10 has. on. its outer periphery suitable gear teeth 22, and carries a. mold block :24 having the usual: face for the natrices, and having an inwardly projectmg porno-n26 fitted. into an opening in the wheel This mold, block 24:- in my invention is provided. with a peculiarly formed slot or mold. space,.indicated at 27, which is adapted. to term the line slug of the desired shape, as hereinafter more fullv described.

Wheel, while the knife 2812115197, he moved; toward or away from the center the Wheel to. allow for different thicknesses of slugs.

'Ehe slug which I desire to cast is shown particularly in Fig. 6. it has a narrow hcdfx Qortion. 30, a T-shapcdhead 81 overhanging the body portion. and having 'on its upper edge characters. indicated at 32, while beneath the ox'enhanging' portions of the head 31 age. narrow verticalt ribs 33 placed atinteiw is along each side of the slug, extending downwardly from the under side of the: head. in thespecific slug shown, the ribs at their upper ends where they join the head project adistance less than that of the head, (say about half thev head projection), and from. the head downward, the ribs in cline l dly, till their ion ends pret eiaialy nit with the side the about was dean it.

Pins 38,

ner. knife- 28 and also carrying a.

some is a carried on forwardly projecting portions of the head, enga e an ejector blade which is guided by the ace 35 of the guideway. In

the regular Mergenthaler mac ine, the mold 24 has a rectangular cavit forming the body of the slug, so spaced mm the center of the mold wheelthat its inner side is in alinement with-the face 35 of the guideway 17', as indicated by dot-and-dash lines at 39 in Fig. 1. Thetrimming knife 28 is fixedso-that its cutting edge s on-this line and the trimming knife 2 "may be adjusted so that it is adapted for the various thickness of the slugs. The ejector blade in such standard machine is held against the face of the guideway by. means of a guide bar 40 hearing against the outer face of the ejector blade and held in'co'ntact' therewith by suitable springs, as indicated at 41, these springs and guide bar being suitably mounted in a casing 42 carried by the guideway 17.

i In order to cast slugs of the character I ha ve shown and described in the ordinary Mergenthaler line casting machine without disturbing the guideway 17 and by means of the usual ejector slide 18, and without disturbing the stationary trimming knife, I provide the special mold adapted to cast this slug with the cavities positioned so that the inner side of the head 31 will be suitably trimmed by the trimmer knife 28 by ..bringing such inner side-to the line 39 in alinement with the face 35 described. The

35 outer trimmer knife 29 is so adjusted as to properly trim the other side'of the head 31 of the slug. This brings the shank30 of the slug a distance awav from the face 35, which makes it"impossible to employ the. usual ejector blade sliding along this face '35. Accordingly, I provide an e ector blade of the following form The blade 45.is provided at its rear end with a -face\46 resting against the face 35 of the guidewav 17, and the outer face 47 of the ejector blade is in alinement with the outer side of theshank 30' of the slug. At the jrearthe' blade .is provided with suitable holes 48, Figs. 1' and 4, which receive the pins 38 of the head 18.- In order to bring the inner side of the blade in alinement with the inner side of the shankof "the slug ;I cut away a portion of 1 the blade, as at 48,- for a distance back of the blade at least equal to the distance the shank stands above the fixed line 39. As

' shown, this cut away portion is formed of such a length that the blade may extend 7 through the mold a distance sufficient to push the slug past the trimmer knives and '60 the frame that holds them. At the forward end of the guideway 17 adjacent the mold, I mount a slide block 50 between the face 35 a'nd the cut away, portion 48 of the ejector blade to insure the blades alining with the Q mold face of'the' mold. The bladeis held tateduntilf tor blade J45." At thisitime the shaft 211s ward,

. sides In operation the mold 24 is brought by I the rotation of the wheel 10 to the spout 52 of the melting pct 54, indicated in Fig. 2.

The mold space is then filled with the molten metal, the matrices, indicated at 55, forming the characters on theslug in the usual manner; -Thereafter the wheel 10 is rorotated, which, through th'e cam 20 and the ejector pushing the slug forwardly from the and at the same time trimming the of the heads 31 by means of these trimming knives 28 and 29. The ejector blade 45 ispreferably made substantially as wide as'the length of the slug, it being held against lateral movement by means of the .pins 38 occupying the holes 48.

It should be noted particularly that the guide on which the ejector-plate slides is on a standard fixed line in the Mergenthaler machine. and I avail myself of this, notwithstanding the peculiar form of the slug, by making a narrow ejector blade and spacing it from the slide, as described." The ejector blade is thus adapted to act on the narrow 'shank' of the slug and, at the same time, is guided by of the support in the machine. Accordingly with my invention it is only necessary to provide the standard Mergenthaler machine withmy'special mold and with my mold 'thelslug-comes opposite the e j ecthe standard fixed plane slide 18, shoves the ejector blade forspaced ejector, as the same ejector guide and operating mechanism and the same trimmingknives may be used in their'standard POSItIOIlS.
